Find the constant of proportionality from a table, one step at a time. Try each problem yourself first, then reach for help only when you want it.
How to use this page
Type your answer in the box if you like. Nothing is graded. Use Hint for a nudge about the next step, Show next step to reveal one worked step at a time, and Reveal answer to check. Hide help / start over tucks everything away again so you can retry.
The big idea: the constant of proportionality k is just the unit rate hiding in the table. Compute k = y divided by x (output divided by input) for a row. If every row gives the same k, the table is proportional and the equation is y = kx.
